EARL E. WRIGHT, OF MANSFIELD, OHIO.

GAS AND GASOLENE ENGINE.

Specification of Letters Patent. Application filed Gotober 27, 1906. Serial No. 340.833.

Patented Nov. 26, 1907.

To all whom it may concern:

Be it kno'wn that I, EARL E. WRIGHT, a citizen `of the United States of America, rcsiding at Mansfield, in the countyof Richl land and State of Ohio, have invented ccrtainnew andv uselul improvements in Gas l and Gasolene Engines, ol' which the following is a speciiication, reference being had therein to the accompanying drawing.

Thisinvention relates to gas and gasolene engines, more particularly of the four cylinder, two cycle type. I

`.The invention has for its primary object i to improve the construction and increase the utility and erliciency of devices of this character.

With these and other objects in View which- Will more readily appear as the invention is the'same consists in the combination and arrangebe hereinafter more i'ully i described, illustrated and then specifically pointed out in the appended claims.

Referring to the drawings forming a part of this specification, like numerals of reference designate corresponding parts throughout the several views, in which- Figure l' is a side elevation of my improved I novel construction,

engine, partly in vertical section; Fig. 2 is 3()` an end View of the engine, F ig. 3 is a vertical and cross sectional View of `the engine; Fig. 4 is a top plan, partly in section; Fig. 5 is a bottom plan partly in section. y

To put my invention into practice, I construct my improved engine 4of two channelshaped frames'l and 2, the frame 2 being inverted upon the frame 1 and secured thereto by bolts and nuts 3, which pass through the flanges f-l of said frames. The channel-shaped frames 1 and 2 forni a boxlike structure or housing for a longitudinally disposed crank sha'lt 5, said shaft being journaled in bearings 6 carried by the ends 7 of the housing, and by partitions e arranged l intermediate the ends of said housing. Uponthe housing is mounted four cylinders 9, said cylinders being secured to the which also serve functionally as guides for the piston cross heads to be presently described. The cylinders 9 are formed with peripheral flanges 11 and iitting over said cylinders and engaging said flanges are water jackets 12, said jackets being connect- I cd'with a suitablr` water supply pipe, where by 'water can be circulated around the 'cylini lresides in the head 2l which has ders to cool the same during the operation of the engine.

The top o'l each cylinder and water jacket is provided with openings 14 to receive a conventional 'form of electric sparking plug, or hot tube` or similar ignition device, but as the construction o'l these sparking )lugs is so well known they are not further illustrated. Each cylinder directly above the flange 11 thereof is rovided with an inlet port 16 and with an ex. iaustl port 17. The inlet port 16 communicates with the housing of the engine b f a curved pipe 18, said pipe passing upwardly from the inverted channel-shaped frame 2. The frame 2 is provided with an inlet port 19, whereby a mixture of air and gas admitted to the heus' ing of the engine will pass upwardly throughl the pipe 18 and into the cylinder 9.

In each cylinder reciprocates a piston con` sisting of heads 2() and 21, sections and packing rings 23, said packing rings being interposed between the peripheral edges of said sections and the heads 2() and 21. 'lhe piston is supported by a piston rod 24. having a shoulder 25 upon which the head 2() rests and a screw-threaded end 26 upon which the head 21 is secured. The headZl serves to retain the sections 22 and the rings 23 upon the head 20 Aand permits of their ready removal at any desired time.

One particular feature of my invention its periphery recessed, as at 27, whereby as the charge of gas enters the cylinder 9 it will be deilectcd upwardly to the `top of the cylinder and prevented from escaping through the exhaust port 17, while the piston is in a lowered position, such as illustrated in Fig. 3.

The piston rod is formed with a cross head 28 having a detachable member 2 9 which provides a slot 30 for a roller 31 carried by the wrist pin 32 carried by the crank shaft 5. 'lhe ends or' the two-part cross head 28 are provided with vertically-disposed grooves 36 to. receive thc tie-rodsl or guides 10, said tierods thus serving to Tuide the crosshead when reciprocated within the housing of the engine. housing `by vcrticall -disposod tic-rods 10, l

',lhis end of the shaft.

carrying upon one-end a gear wheel 40,.

meshing with an idler `gear wheel 43, journaled at the end of the-housing, -said idler gear Wheel also meshing in turn with the gear Wheel 38 of the sha-ft 5I The shaft 39 is provided for controlling the electrical ignition devices, and the water pump ofthe.

ing its charge, the piston of saidcylinder is.

. elevated. As the piston travels upwardly closing the inlet and exhaust ports lot the cylinder, the charge of gas wi thin the cylinder is compressed and ignited, causing explosion,

which drives the piston downwardly in the cylinder. haust slightly in advance of^the opening of the inlet port and as it is ready tb receive a fresh charge of gas. ln providing the piston head 21 with a recess 27, l obviate the necessity for providing said head with flanges or deilectors of any type, as the shape of the recess in said head causes the gas to travel upwardly within the cylinder, and before it can descend the exhaust port is closed.

The two-part cross-head 28 of the piston rod 24 provides a relatively long pistoii head, and thus also provides a correspondingly long bearing and insures a positive centering of the piston rod within its cylinder during the stroke, thereby dispensing with the wear and tear of the cylinder heretofore experi.- enced in unguidedpiston rods.

From the foregoing description taken in connection with the drawings it will be Vobserved that l have devised an extremely simple engine, having .comparatively y'few parts which can lble easily and quickly assembled to providey an eiiicient and durable engine.

What I claim as new and desire tov secure by Letters Patent, is

1. In an engine of the classdescribed, a housing in two portions and having half bearings in their. adjacenti'aces, cylinders mounted upon said housing, tie rods spaced apart and extending through said housing and connected to said cylinders, pistons operating in said cylinders, piston rods connected to said pistons and provided with transverse slotted cross-heads sldabl en- I raging said tie rods, and a shaft journa ed in eid housing bearings and provided with .cranks operating in'said slotted heads.

The cylinder is permitted to eX- housing in'two portions having haltl bearings in their adjacent faces, one housing portion closed at its outer side and the other housing portion open at its outer side, cylinders mounted upon the open side of said housing portion, tie rods spaced apart and extending through the closed side of said housing portion and connected to said cylinders, pistons operating in said cylinders, piston rods connected to said pistons and provided with transverse slotted heads slidably'v engaging said tie rods, and ashaft journaled in said housing bearings and provided with cranks operating 'in said slotted heads.

3. In an engine of the class described,'a housing in two portions and. divided bytr/ansv'erse partitions into a plurality of compartments with shaft bearings in said partitions, a cylinder mounted upon said housing over each of said compartments, tie rpds and provided with a" slotted transverse head'.

slidably engaging eah pair of the tie rods in said compartments, and a shaft journaled in.

the bearings in said partitions and with a drank with-in each oi said compartments and engaging said slotted heads.

4. ln an engine of the class described, a housing in two portions having half bearings in Atheir adjacent faces and divided by trans- V'spaced apart in pairs'and extending through verse partitions into a plurality of cmpartments with half bearings between the adjacent faces of the partitions, a cylinder mounted upon said housing over each of'said compartments, tie rods spaced apart in pairs and 4 extending through ysaidhousing in each of said compartments and connected respectively to said cylinders, a piston operating in i each of said cylinders and consisting of spaced heads and a cylindrical intermediate portion .whereby a relatively large bearing surface isv produced, a piston rod having an intermediate. shoulder bearing 'against one of said piston heads and Ithreaded at one terminal into the other piston head and with a slotted V head at the other 'terminal slidably engaging each pair of the tie rods, a shaft journaled in the bearings in said housing and in the partitions thereoil and provided with crank pins respectively engaging the slotted heads of the several piston rods. y

'ln testimony whereof l ai'iix my signature in the presence of two witnesses.
